Patients with leukemic non-nodal mantle cell lymphoma (nnMCL) typically exhibit an indolent clinical course, and when asymptomatic and without treatment indications, a watchful observation follow-up can be adopted. This article presents a retrospective summary of a case of nnMCL, misdiagnosed as chronic lymphocytic leukemia (CLL) and carrying a TP53 mutation, along with a literature review. The case highlights the importance of differential diagnosis between nnMCL and CLL, and suggests that for nnMCL patients, the presence of high-risk biological markers such as TP53 mutations does not necessarily indicate an immediate need for treatment; rather, a strict watch-and-wait strategy may be a more appropriate option.

Objective:To explore the impact of age on the genetic variant spectrum and prognosis of patients with previously untreated Diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective analysis was conducted on the clinical data and follow-up information of 254 previously untreated DLBCL patients from 14 hospitals in the Jiangsu Cooperative Lymphoma Group (JCLG) enrolled from July 2018 and July 2023. Following extraction of DNA from tumor tissue samples, next-generation sequencing (NGS) technique was employed to analyze the genetic variant spectrum of the DLBCL patients, with an evaluation of the relationship between age and genetic variants as well as prognosis. This study was approved by the Medical Ethics Committee of the Affiliated Hospital of Nantong University (Ethics No.: 2023-K048-01).Results:The median age of the 254 DLBCL patients was 62 years old, with 55% of patients aged 60 years or above. Clinical evaluation showed that younger (< 60 years) patients had higher complete response (CR) (70% vs. 59%), and objective response rate (ORR) (88% vs. 79%) than older patients, though the difference between the two groups was not statistically. Survival analysis indicated that both the five-year overall survival (OS) (82.7% vs. 71.7%, P=0.006) and progression-free survival (PFS) (70.6% vs. 50.2%, P<0.05) rates were significantly higher in younger patients. NGS showed that 99.6% of the patients harbored genetic variants, with PIM1, KMT2D, TP53, MYD88, and CD79B being the most common genes. Age significantly affected the variant frequency of certain genes, with MYC variants serving an adverse prognostic factor for OS in younger patients ( P=0.001), while TP53 ( P=0.024) and BCL2 ( P=0.002) variants significantly impacted OS in older patients. Prognostic analysis identified age ≥ 60 years ( HR=3.439, 95% CI=1.318~9.874), presence of B symptoms ( HR = 2.871, 95% CI=1.133~7.307), and elevated lactate dehydrogenase ( HR=3.528, 95% CI=1.231~10.66) as independent adverse prognostic factors. Conclusion:Age, genetic variants, and clinical factors may significantly affect the prognosis of the DLBCL patients. Younger patients have better survival compared to older patients. Variants of the MYC, BCL2, and TP53 genes are closely associated with poor prognosis.

Objective To discuss the application value of CT and DSA multimodal image fusion technology in endovascular interventional therapy for arterial occlusive lesions of lower extremities and to evaluate its efficacy and safety so as to provide a scientific basis for clinical decision-making.Methods A total of 283 lower limbs with arterial complete occlusive lesions,who received treatment at Affiliated Baiyun Hospital of Guizhou Medical University hospital from January 2020 to December 2023,were selected for this study.The 283 diseased lower limbs were randomly divided into study group(n=142)and control group(n=141).In the study group the endovascular interventional therapy assisted by CT and DSA multimodal image fusion technology was adopted,while in the control group the traditional DSA-guided endovascular interventional therapy was employed.The imaging parameters,surgical success rates,X-ray exposure doses,time spent for operation,incidence of postoperative complications,changes of ankle-brachial index(ABI),primary patency rate,assisted primary patency rate,and secondary patency rate were compared between the two groups.Results The surgical success rate in the study group was 96.47％,which was significantly higher than 87.94％in the control group(P＜0.05).The mean time spent for operation in the study group was(125.42±23.74)minutes,which was shorter than(147.81±29.33)minutes in the control group.The mean X-ray exposure dose in the study group was(2 856.34±427.82)mGy·cm2,which was lower than(3 674.53±512.60)mGy·cm2 in the control group.The incidence of postoperative complications in the study group was 4.23％,which was significantly lower than 12.57％in the control group(P＜0.05).The ABI values of the affected limbs in the study group and control group increased from preoperative(0.65±0.15)and(0.60±0.18)respectively to postoperative(1.09±0.32)and(0.90±0.28)respectively.The postoperative ABI value in the study group was higher than that in the control group(P＜0.05).The postoperative 12-month primary patency rate,assisted primary patency rate and secondary patency rate in the study group were 78.17％,85.92％and 90.14％respectively,which were better than 67.38％,75.89％and 80.85％respectively in the control group.Conclusion For arterial occlusive lesions of lower extremities,endovascular interventional therapy with the help of CT and DSA multimodal image fusion technology has high surgical success rates,low incidence of complications,and satisfactory revascularization rate.This technology provides new idea and method for the treatment of arterial occlusive lesions of lower extremities with high clinical safety.Therefore,this technology is worthy of clinical promotion and application.

Objective: To understand 24 h physical activity levels of children aged 8-9 years in Pudong New Area and to explore its association with metabolic syndrome, so as to provide scientific basis for children s participation in physical activities and reducing the risk of metabolic syndrome. Methods: A stratified cluster random sampling method was adopted to select 13 schools in Pudong New Area, Shanghai. A total of 2 013 primary school students aged 8-9 years old were included as the research subjects. During September 2021 to December 2022, Actigraph GT3X accelerometer, height measuring gauge, electronic sphygmomanometer and waist circumference tape was used to measure physical activity, height, blood pressure and waist circumference, respectively. A total of 5 mL of venous blood was collected from students, and the levels of triglycerides (TG), highdensity lipoprotein cholesterol (HDL-C) and fasting plasma glucose (FPG) were detected, and online questionnaires were conducted. The ttest and oneway ANOVA were employed to compare the differences in 24 h physical activity levels among children with different characteristics. Multivariate Logistic regression was used to analyze the association between the 24 h physical activity levels and metabolic syndrome as well as its components. Results: Among primary school students, the average daily time of moderate to vigorous physical activity (MVPA) was (34.25±13.49)min, the attainment rate was 1.59%. The average daily sleep (SLP) time was (538.27±28.53) min, attainment rate was 1.89%. The detection rates of metabolic syndrome, abdominal obesity (AO), elevated blood pressure (BP), elevated TG, low HDL-C, and elevated FPG were 2.48%, 34.53%, 10.38%, 10.73%, 1.24% and 0.70%, respectively. Multivariate Logistic regression analysis showed that, for every 10minute increase in sedentary behavior (SB) time, the risks of AO, elevated BP, and elevated TG increased by 2% ( OR=1.02, 95%CI =1.01-1.04), 5% ( OR=1.05, 95%CI =1.01-1.08), and 6% ( OR= 1.06, 95%CI =1.02-1.11), respectively ( P <0.05). For every 10minute increase in MVPA time, the risk of metabolic syndrome decreased by 27% ( OR=0.73, 95%CI=0.57-0.93, P <0.05). For every 10 minute increase in SLP time, the risks of AO, elevated BP, and metabolic syndrome decreased by 16% ( OR=0.84, 95%CI =0.80-0.88), 9% ( OR=0.91, 95%CI =0.82- 0.99 ), and 15% ( OR=0.85, 95%CI =0.77-0.94), respectively （P <0.05). Conclusions The time of MVPA and SLP are seriously insufficient among children aged 8-9 years in Pudong New Area. There is an association between physical activity levels and metabolic syndrome as well as its components. Increasing the time of MVPA and SLP is of great significance for maintaining a relatively low risk of metabolic syndrome in children.

Objective:To explore the impact of previous cytomegalovirus (CMV), herpes simplex virus (HSV), and rubella virus (RV) infection on pregnancy outcomes in infertile women undergoing the first in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) treatment. Methods:A retrospective cohort study was conducted to analyze the clinical data of women who underwent IVF/ICSI-ET for the first time at the Reproductive Medicine Center, the First Affiliated Hospital of Zhengzhou University from December 2017 to December 2022. The patients were divided into CMV-IgG (+) group ( n=154), RV-IgG (+) group ( n=86), HSV-IgG (+) group ( n=93) and IgG all-negative group ( n=172). The pregnancy outcomes of the patients in the virus-only infection group and the IgG all-negative group were compared. Patients who were previously co-infected with CMV and HSV were classified as the CMV+HSV-IgG (+) group ( n=344), and the pregnancy outcomes of patients with previous CMV and HSV co-infection and those with infection alone were further compared. Results:The two pronuclei (2PN) fertilization rate [63.90% (1 195/1 870)], the clinical pregnancy rate [51.30% (79/154)], and the live birth rate [45.45% (70/154)] of the CMV-IgG (+) group were significantly lower than those of the IgG completely negative group [68.68% (1 469/2 139), P=0.001; 68.60% (118/172), P=0.001; 61.05% (105/172), P=0.005]. The 2PN fertilization rate [61.62% (729/1 183)], the clinical pregnancy rate [50.54% (47/93)], and the live birth rate [43.01% (40/93)] of the HSV-IgG (+) group were significantly lower than those of the IgG completely negative group [68.68% (1 469/2 139), P=0.001; 68.60% (118/172), P=0.004; 61.05% (105/172), P=0.005]. There were no statistical differences in the 2PN fertilization rate, the clinical pregnancy rate, and the live birth rate between the RV-IgG (+) group and the IgG completely negative group (all P>0.05). Compared with the IgG completely negative group, there were no significant differences in the risk of complications such as gestational diabetes, hypertensive disorders of pregnancy and neonatal outcomes in the CMV-IgG (+) group, RV-IgG (+) group, and HSV-IgG (+) group (all P>0.05). Multivariate logistic regression analysis showed that CMV-IgG (+) ( OR=0.453, 95% CI: 0.280-0.734, P=0.001; OR=0.515, 95% CI: 0.321-0.825, P=0.006), HSV-IgG (+) ( OR=0.425, 95% CI: 0.245-0.738, P=0.002; OR=0.447, 95% CI: 0.259-0.771, P=0.004) and CMV+HSV-IgG (+) ( OR=0.491, 95% CI: 0.329-0.733, P=0.001; OR=0.528, 95% CI: 0.357-0.780, P=0.001) were all independent influencing factors of patients' clinical pregnancy and live birth. There were no statistical differences in the clinical outcomes between the previous CMV and HSV co-infection group and the single infection group ( P>0.05). Conclusion:Previous CMV or HSV infection alone reduced the fertilization rate, the clinical pregnancy rate and the live birth rate of patients undergoing IVF/ICSI-ET treatment, but had no significant impact on pregnancy complications and neonatal outcomes. Pregnancy outcomes of patients with previous CMV and HSV co-infection were similar to those with infection alone.

Objective:Comparative efficacy and safety profiles of tenofovir disoproxil fumarate (TDF) versus tenofovir alafenamide fumarate (TAF) in chronic hepatitis B (CHB) patients with high viral load.Methods:CHB patients with high viral load (hepatitis B virus (HBV) DNA>7 lg IU/mL) receiving TDF ( n=155) or TAF ( n=157) monotherapy were included between December 1st, 2022 and December 1st, 2023, to compare the rates of undetectable HBV DNA (<20 IU/mL), the alanine transaminase (ALT) normalization rate, hepatitis B e antigen (HBeAg) seroconversion rate, renal function and lipid profiles at 48 weeks of treatment. The statistical analysis was performed by the two independent samples t test, Mann-Whitney U test, chi-square test or Fisher′s exact probability test. Results:At week 48 of treatment, the TDF group achieved significantly higher HBV DNA undetectability rates (49.03%(76/155) vs 29.30%(46/157)) and greater mean reduction ((6.05±0.81) lg IU/mL vs (5.57±1.02) lg IU/mL) than the TAF group ( χ2=12.75, t=-4.65, both P<0.001). The ALT normalization rate of patients in the TDF and TAF groups were 77.19%(88/114) and 72.50%(87/120), and HBeAg seroconversion rates were 4.00%(6/150) and 2.67%(4/150), respectively, with no statistically significant differences between the two groups (all P>0.05). The differences in the changes and abnormal rates of serum creatinine and estimated glomerular filtration rate between the two groups of patients were not statistically significant (both P>0.05). The magnitude of decrease (0.15(-0.02, 0.38) mmol/L vs 0.06(-0.06, 0.20) mmol/L) and abnormal rate (27.73%(33/119) vs 16.39%(20/122)) in high-density lipoprotein cholesterol in the TDF group was higher than those in the TAF group, while the increases in low-density lipoprotein cholesterol (-0.09(-0.39, 0.25) mmol/L vs 0.05(-0.31, 0.42) mmol/L), total cholesterol (TC) (-0.23(-0.75, 0.23) mmol/L vs 0.08(-0.35, 0.57) mmol/L), and triglyceride (-0.12(-0.40, 0.06) mmol/L vs 0.00(-0.19, 0.24) mmol/L), as well as the abnormal rate of TC (4.31%(5/116) vs 15.75%(20/127)), in the TDF group were lower than those in the TAF group ( Z=-3.19, χ2=4.51, Z=2.17, Z=4.09, Z=3.71, χ2=8.59, all P<0.05). Conclusion:TDF demonstrated superior efficacy and better safety profiles compared to TAF in high viral load CHB patients.

Objective:To explore the longitudinal predictive relationship between self-neglect and frailty among older adults.Methods:Data were drawn from the Chinese Longitudinal Healthy Longevity Survey conducted in 2011 (T1), 2014 (T2), and 2018 (T3). A total of 1 495 older adults aged≥65 years at T1 who participated in three consecutive surveys and had no missing key variables were included. General demographic information, self-neglect scores, and frailty status were extracted. Spearman correlation analysis was used to examine the association between self-neglect and frailty. Cross-lagged analysis was employed to investigate the potential causal relationship between the two variables.Results:The self-neglect scores for 1 495 older adults at T1, T2, and T3 were (2.84±1.39), (2.47±1.30), and (2.41±1.20), respectively, showing a declining trend. The frailty scores at T1, T2, and T3 were 0 (0, 1.00), 0 (0, 2.00), and 1.00 (0, 2.00), respectively, indicating an increasing trend. Cross-lagged analysis revealed that self-neglect at T1 positively predicted frailty at T2 (β=0.076, P=0.004). Frailty at both T1 and T2 positively predicted self-neglect at T2 (β=0.057, P=0.044) and T3 (β=0.058, P=0.029), respectively. Conclusions:Frailty among older adults positively predicts self-neglect, and self-neglect also has a certain predictive effect on frailty. Medical staff should strengthen early screening and intervention for frailty in older adults to delay the occurrence and progression of self-neglect.

Objective:To explore the impact of previous cytomegalovirus (CMV), herpes simplex virus (HSV), and rubella virus (RV) infection on pregnancy outcomes in infertile women undergoing the first in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) treatment. Methods:A retrospective cohort study was conducted to analyze the clinical data of women who underwent IVF/ICSI-ET for the first time at the Reproductive Medicine Center, the First Affiliated Hospital of Zhengzhou University from December 2017 to December 2022. The patients were divided into CMV-IgG (+) group ( n=154), RV-IgG (+) group ( n=86), HSV-IgG (+) group ( n=93) and IgG all-negative group ( n=172). The pregnancy outcomes of the patients in the virus-only infection group and the IgG all-negative group were compared. Patients who were previously co-infected with CMV and HSV were classified as the CMV+HSV-IgG (+) group ( n=344), and the pregnancy outcomes of patients with previous CMV and HSV co-infection and those with infection alone were further compared. Results:The two pronuclei (2PN) fertilization rate [63.90% (1 195/1 870)], the clinical pregnancy rate [51.30% (79/154)], and the live birth rate [45.45% (70/154)] of the CMV-IgG (+) group were significantly lower than those of the IgG completely negative group [68.68% (1 469/2 139), P=0.001; 68.60% (118/172), P=0.001; 61.05% (105/172), P=0.005]. The 2PN fertilization rate [61.62% (729/1 183)], the clinical pregnancy rate [50.54% (47/93)], and the live birth rate [43.01% (40/93)] of the HSV-IgG (+) group were significantly lower than those of the IgG completely negative group [68.68% (1 469/2 139), P=0.001; 68.60% (118/172), P=0.004; 61.05% (105/172), P=0.005]. There were no statistical differences in the 2PN fertilization rate, the clinical pregnancy rate, and the live birth rate between the RV-IgG (+) group and the IgG completely negative group (all P>0.05). Compared with the IgG completely negative group, there were no significant differences in the risk of complications such as gestational diabetes, hypertensive disorders of pregnancy and neonatal outcomes in the CMV-IgG (+) group, RV-IgG (+) group, and HSV-IgG (+) group (all P>0.05). Multivariate logistic regression analysis showed that CMV-IgG (+) ( OR=0.453, 95% CI: 0.280-0.734, P=0.001; OR=0.515, 95% CI: 0.321-0.825, P=0.006), HSV-IgG (+) ( OR=0.425, 95% CI: 0.245-0.738, P=0.002; OR=0.447, 95% CI: 0.259-0.771, P=0.004) and CMV+HSV-IgG (+) ( OR=0.491, 95% CI: 0.329-0.733, P=0.001; OR=0.528, 95% CI: 0.357-0.780, P=0.001) were all independent influencing factors of patients' clinical pregnancy and live birth. There were no statistical differences in the clinical outcomes between the previous CMV and HSV co-infection group and the single infection group ( P>0.05). Conclusion:Previous CMV or HSV infection alone reduced the fertilization rate, the clinical pregnancy rate and the live birth rate of patients undergoing IVF/ICSI-ET treatment, but had no significant impact on pregnancy complications and neonatal outcomes. Pregnancy outcomes of patients with previous CMV and HSV co-infection were similar to those with infection alone.
